This research study seeks to understand brain development during childhood and brain changes over time.

We are now recruiting children ages 4-14 with ADHD symptoms or an ADHD diagnosis. Your child may be eligible to participate in 1-2 outpatient visits to the NIH Clinical Center in Bethesda, Maryland. Participation includes an interview with parents and child, psychological testing, non-invasive brain scans, and genetic testing (from a saliva or blood sample.).

There is no cost to participate. Compensation is provided. Parental permission is required.

To find out if you qualify, email NIMH or call 1-301-496-0851 [TTY: 1-866-411-1010].
